This screwdriver, made of stainless steel with copper alloy, is a special one. The screwdriver has a motor and motion activation. Simply turning your hand a bit while holding the ES121 is enough to let it solve the hard work. The screwdriver makes it very easy to turn screws. On the OLED screen you can see exactly how everything is going.
In contrast to a cordless drill it offers much more precision, because the feeling when tightening is very clear. In addition, the screwdriver also functions as a normal screwdriver, to dose the applied force very precisely.
In addition, the ES121 is open source, so all software can be customized as desired.
